Hi, love this library, thank you for all the great work. I'm trying to use the fill features to add some shading within plotted shapes and noticing that the fill doesn't seem to be as precise for the concave shapes I'm drawing.

See this image:

The red line should be the boundary of the shape, and I was hoping to fill within the boundary. You can see that the fill is spilling out from the shape to make it more square (and it seems to be a different opacity).

Currently I'm drawing the outline as a clockwise loop. The fill is drawn using plotShaded with the exact same clockwise loop of points.

I was wondering if this is user error or a known issue or if there were any work arounds here? I could tesselate this shape by hand,

Thanks again!

Edit, also just noticed that the fill on the top doesn't line up either:
